The hosts were on top early doors and they thought they should have had a penalty when Davide Astori appeared to handle inside his own area – but the referee ruled it accidental after the ball bounced up to his hand from his leg.

Kwadwo Asamoah fired over and Paulo Dybala was inches wide with a curling strike as Juve pressed for the opener before Khedira stepped up to give them the lead at the break.

Nikola Kalinic drew the visitors’ level on 70 minutes, powerfully heading home from a corner – but they would only be level for four minutes.

After a goalless opening half the Yellow and Reds were much more aggressive after the restart and were rewarded as they blitzed their way to victory.

The opener came when Danilo mistimed his sliding tackle and took down Dzeko, allowing sub Perotti to convert from the spot.

A second spot-kick and goal arrived shortly after as Salah was felled by Emmanuel Badu, allowing Perotti grab his double – becoming the first man to convert two penalties in the same Serie A match since Vincenzo Montella in 2002.

Dzeko side-footed home a third as the Udinese defence began to capitulate and it was left to Salah to seal the rout late on.
